Letters Patent No. 100,314, dated Merch 1, 1870.

IMPROVEMENT IN ROBE' FOR DOOR-ENOES.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern.'

Be it known that I, W. T. MUNGER, of New Britain, in the county of Hartford, and Stateof Oonnecticut, have invented an Improvement in Roses for Door-Knobs, andthe following is declared to be a correct description thereof'.

This invention is devised for securing the screw that holds the knob to the spindle, and for preventing said screw dropping out. or coming into Contact with the fingers in grasping the knob.

My invention consists in a two-part sectional rose or escutcheon for the spindle and knob-shank, the main portion of the rose having a. flange or cylinder partially surrounding the shank of the knob, and the remainder of the said cylinder being upon a disk, through which the spindle passes, so that when the parts are together the cylindrical flange surrounds the shank and covers the screw that passs through the same, preventing it from'falling out or Corning in contact with the lingers, should it become loose from the frequent handling of the knob.

In ythe drawinga. is the knob;

b, the shank; and

c, the spindle, united to the shank by the screw e.

These parts are shown seotionally in Figure 1, and

l may he otl any usual or desired character.

The main portion, d, of the rose is shown detached in Figure 2, and -the disk and secondary portion, f, of the rose is shown in Figure 3.

The cylindrical portion of the rose, into which the shank b passes, aud which covers .up or secures the screw e, is made of two parts, the. portion'i being formed as a llange upon the rose d, and the otlrer'portion, r, heing formed upon the disk f, and when the parts are together vthe portion fr passes into the part o of the'opening in the rose d, completing the cylinder that'surronnds the shank b.

1n putting the knob on thespindle, first slip the part d of the rose upon the shank b, and pass the disk f upon the spindle c; put theknob upon 'the spindle, enter the screw e' firmly, to secure the handle and spindle; then slip the rose d back against the door and secure it by screws through the holes s s s, or otherwise.

By this construction the disk fprevents end motion to the spindle and knob, and the cylindrical flange formed bythe sections o and r supports the shank against lateralI movement, rand keeps -the screw ein place. I claim as myv invention- The rose, formed of the parts d and f, upon which are the sections 'i and 'rof the cylindrical ilange that surrounds the end of the shank, and retains the screw c,A should it become loose, as specified.

Signed this 23d day of December, 1869.
